Numerical simulation of the High Plains regional aquifer, northwestern Oklahoma
J.S. Havens, S. C. Christenson
1984, Water-Resources Investigations Report 83-4269
The High Plains aquifer consists of the Tertiary Ogallala Formation and overlying Quaternary alluvium and terrace deposits together with parts of underlying rocks. Before extensive irrigation in the 1960's, recharge from precipitation was balanced by natural discharge. Baseflow was estimated as approximately 118 cubic feet per second in 1980. A...
Statistical models for estimating flow characteristics of Michigan streams
D. J. Holtschlag, H.M. Croskey
1984, Water-Resources Investigations Report 84-4207
Multiple-regression equations were developed to estimate flow characteristics at ungaged sites. Several readily measureable basin characteristics and an areal adjustment factor are required in the equations. Equations have been prepared to estimate mean and mean monthly flow, flow duration, low flow, peak flow, and flood volume. The precision of the...
Trace metals in Suisun Bay, California: A preliminary report
S. N. Luoma, P. V. Cascos, R. M. Dagovitz
1984, Water-Resources Investigations Report 84-4170
A 5-month partial study (February to July 1983) was completed in Suisun Bay, a shallow embayment of San Francisco Bay, Calif., to determine characteristic heavy metal concentrations present in sediments and organisms (Corbicula clams) prior to possible discharge of San Luis Drain irrigation tile return water. Preliminary results show sediments...
Steady-state computer model of the water-table aquifer in the Mullica River basin, the Pine Barrens, New Jersey
A.W. Harbaugh, C.L. Tilley
1984, Water-Resources Investigations Report 84-4295
A two-dimensional steady-state model of the water-table aquifer of the Mullica River basin was made to evaluate the flow system and data required to simulate it. The Mullica River basin covers 570 sq mi and is drained by numerous shallow streams. The water-table aquifer consists of sand and gravel intermixed...
Reconnaissance geologic map of the Noatak C5, D5, D6, and D7 quadrangles, Alaska
C.F. Mayfield, Inyo Ellersieck, I.L. Tailleur
1984, Open-File Report 84-396
This map covers the northwestern part of the Noatak 1:250,000-scale quadrangle (fig. 1, sheet 1). The area has low topographic relief that largely consists of gently sloping hills separated by broad expanses of tundra growing on unconsolidated surficial materials. Elevations range from sea level up to 475 m (1,456 ft.)...
Evaluation of the ground-water resources of parts of Lancaster and Berks Counties, Pennsylvania
J. M. Gerhart, G.J. Lazorchick
1984, Water-Resources Investigations Report 84-4327
Secondary openings in bedrock are the avenues for virtually all ground-water flow in a 626-sqare-mile area in Lancaster and Berks Counties, Pennsylvania. The number, size, and interconnection of secondary openings are functions of lithology, depth, and topography. Ground water actively circulates to depths of 150 to 300 feet below land...
Wilderness mineral potential: Assessment of mineral-resource potential in U.S. Forest Service lands studied in 1964-1984: Volume 2
S.P. Marsh, S.J. Kropschot, R. G. Dickinson, editor(s)
1984, Professional Paper 1300-2
The summaries in these volumes, which have been organized alphabetically by state, include a description of the character and geologic setting, a discussion of the resource potential, and a reference list of selected material published as part of the wilderness program. Many of the summaries include suggestions for further study....
Gazetteer of hydrologic characteristics of streams in Massachusetts — Coastal river basins of the North Shore and Massachusetts Bay
S. W. Wandle
1984, Water-Resources Investigations Report 84-4281
The coastal river basins of the North Shore and Boston Bay include streams draining the Parker River (60.4 square miles), Rowley River (9.9 square miles), Ipswich River (156 miles), Mystic River (66.0 square miles), Charles River (311 square miles), Neponset River (117 square miles), Weymouth Fore and Weymouth Back Rivers...
Gazetteer of hydrologic characteristics of streams in Massachusetts — Blackstone River basin
S. W. Wandle, A. F. Phipps
1984, Water-Resources Investigations Report 84-4286
The Blackstone River basin encompasses 335 square miles in south-central Massachusetts, including parts of Bristol, Middlesex, Norfolk, and Worcester Counties. Drainage areas, using the latest available 1:24,000 scale topographic maps, were computed for the first time for streams draining more than 3 square miles and were recomputed for data-collection sites....
